A body bonding installation part, a bonding fixing assembly and a car

Abstract

This invention discloses a vehicle body grounding mounting component, a grounding fixing assembly, and an automobile. The component includes a grounding mounting component body with a protruding structure at its lower part for connection to a vehicle body support component. A groove is provided at the upper part of the grounding mounting component body, with an anti-rotation slot at the bottom of the groove and a clearance groove on the groove wall. When a wire harness grounding terminal is placed in the groove, the groove, slot, and clearance groove limit the movement of different wire harness grounding terminals, preventing rotation and thus meeting the anti-rotation requirements of different wire harness grounding terminals. The wire harness grounding terminal is connected to the grounding mounting component via a connector, and to the vehicle body support component via the protruding structure. This allows the end of the connector to be positioned between the grounding mounting component and the vehicle body support component, eliminating the need for bolt clearance holes on the vehicle body support component and meeting the vehicle's interior waterproofing requirements.

Description

Technical Field

[0001] This invention relates to the field of new energy vehicle body grounding installation technology, and in particular to a body grounding installation part, grounding fixing assembly, and automobile. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the development of lightweight vehicles, more and more cars are now using unibody die-cast bodies. Compared with traditional bodies, unibody die-cast bodies are lighter, but thicker, which makes traditional riveted bolt grounding structures and welded stud grounding structures unusable.

[0004] Specifically, traditional automotive bodies use steel grounding studs for welding, while unibody die-cast bodies are made of aluminum alloy. Steel and aluminum have different electrical conductivity, which can easily lead to grounding failures. Therefore, steel grounding studs are unsuitable for aluminum alloy bodies. Traditional automotive body riveting grounding studs are generally suitable for sheet metal with a thickness of 0.7-2mm, but aluminum alloy bodies are typically over 3mm thick, making riveting grounding bolts also unsuitable.

[0005] To address the aforementioned issues, a grounding structure suitable for die-cast aluminum alloy car bodies has emerged. This structure includes fastening screws, high-voltage wiring harnesses, high-voltage grounding components, and load-bearing components. The high-voltage grounding components have bolt holes, and the fastening screws pass through the ends of the high-voltage wiring harnesses and are fixed in the bolt holes. The two sides of the high-voltage grounding components are connected to the load-bearing components via MIG argon shielded welding. This resolves the contradiction between the torque generated by directly welding the fastening screws to the load-bearing components and the thickness of the load-bearing components, and solves the problem of the difficulty in implementing high-voltage grounding for aluminum alloy car bodies. However, this grounding structure requires bolt clearance holes to be provided on the load-bearing components, thus failing to meet the waterproofing requirements of automotive interiors and the anti-rotation requirements of different wiring harness grounding terminals. Summary of the Invention

[0006] To address the aforementioned problems, this invention proposes a vehicle body grounding mounting part, a grounding fixing assembly, and a vehicle. By providing grooves, slots, and clearance slots on the upper part of the grounding mounting part, the anti-rotation requirements of different wire harness grounding terminals can be met, and clearance holes are not required on the vehicle body supporting parts, thereby meeting the waterproofing requirements of the vehicle interior.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Firstly, a vehicle body grounding mounting component is proposed, comprising a grounding mounting component body, a protruding structure at the lower part of the grounding mounting component body for connecting with a vehicle body load-bearing component, a groove at the upper part of the grounding mounting component body, an anti-rotation slot at the bottom of the groove, and a clearance groove on the groove wall. The groove is used to place a wire harness grounding terminal. When a wire harness grounding terminal without an anti-rotation claw is placed in the groove, the groove wall can provide a limit for the two side walls of the wire harness grounding terminal. When a wire harness grounding terminal with an anti-rotation claw at one end is placed in the groove, the anti-rotation claw of the wire harness grounding terminal can be engaged with one end of the groove. When a wire harness grounding terminal with an inclined anti-rotation claw is placed in the groove, the anti-rotation claw of the wire harness grounding terminal can be connected with the anti-rotation slot, and the protruding part of the wire harness grounding terminal can be located in the clearance groove to prevent different wire harness grounding terminals from rotating.

[0009] Secondly, a vehicle body grounding fixing assembly is proposed, including a vehicle body grounding mounting part, a wire harness grounding terminal, and a vehicle body supporting part as proposed in the first aspect; a protruding structure of the vehicle body grounding mounting part is connected to the vehicle body supporting part; the wire harness grounding terminal is placed in a groove of the vehicle body grounding mounting part and connected to the body of the grounding mounting part through a connector; when the wire harness grounding terminal is a wire harness grounding terminal without anti-rotation claws, the groove wall provides limiting for the two side walls of the wire harness grounding terminal; when the wire harness grounding terminal is a wire harness grounding terminal with anti-rotation claws at one end, the anti-rotation claws of the wire harness grounding terminal are engaged with one end of the groove; when the wire harness grounding terminal is a wire harness grounding terminal with inclined anti-rotation claws, the anti-rotation claws of the wire harness grounding terminal are connected to the anti-rotation groove, and the protruding part of the wire harness grounding terminal is located in the clearance groove.

[0010] Thirdly, a car is proposed, including a body grounding fixing component proposed in the second aspect.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The present invention provides a groove on the upper part of the grounding installation part body, an anti-rotation slot at the bottom of the groove, and clearance slots on the groove walls. When the wire harness grounding terminal is placed in the groove, the groove, slot and clearance slot can limit the different wire harness grounding terminals to prevent the wire harness grounding terminals from rotating, thereby meeting the anti-rotation requirements of different wire harness grounding terminals.

[0013] 2. The present invention connects the grounding terminal of the wire harness to the grounding mounting part through a connector. A protruding structure is provided on the lower part of the grounding mounting part. The protruding structure is connected to the vehicle body load-bearing part, so that the end of the connector can be located between the grounding mounting part and the vehicle body load-bearing part. Therefore, it is not necessary to open bolt clearance holes on the vehicle body load-bearing part, thereby meeting the indoor waterproofing requirements of automobiles.

[0014] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] Example 1

[0028] like Figure 5 , Figure 6 , Figure 7 As shown, there are three main types of wiring harness grounding terminals used in automobiles. The first type, wiring harness grounding terminal 5, is a wiring harness grounding terminal without anti-rotation claws. The main body of this terminal is rectangular, circular, or other shapes. The wiring harness is connected to the middle part of one end of the terminal body. By limiting the two side walls of the terminal body, rotation of the wiring harness grounding terminal can be prevented. The second type, wiring harness grounding terminal 6, is a wiring harness grounding terminal with anti-rotation claws at one end. The anti-rotation claws and the wiring harness are located at opposite ends of the terminal body. By fixing the anti-rotation claws, rotation of the terminal body can be prevented. In addition, the other two... Each end is also provided with an upwardly bent limiting bend. Besides fixing the anti-rotation claw at one end, the two limiting bends can also be connected to external parts to prevent the wire harness ground terminal from rotating. The third type of wire harness ground terminal 7 is a wire harness ground terminal with inclined anti-rotation claws. The main body of this wire harness ground terminal is rectangular. The wire harness is connected to one end of the rectangular main body of the wire harness ground terminal. Anti-rotation claws are provided on the two long sides of the rectangular main body. Upwardly bent limiting bends are provided at two adjacent ends of the end connecting the wire harness. By fixing the two anti-rotation claws or connecting to external parts through the two limiting bends, the rotation of the wire harness ground terminal can be prevented. When the rotation of the wire harness ground terminal is prevented by fixing the two anti-rotation claws, the two limiting bends serve as the protruding parts of the wire harness ground terminal with inclined anti-rotation claws.

[0029] To secure the grounding terminals of the three different wire harnesses and meet their anti-rotation requirements, this embodiment discloses a vehicle body grounding mounting component, such as... Figure 1 , Figure 2As shown, the device includes a grounding mounting component body 3. A protruding structure 3.6 is provided at the lower part of the grounding mounting component body 3. The protruding structure 3.6 is used to connect with the vehicle body supporting component 4. A groove 3.5 is provided at the upper part of the grounding mounting component body 3. An anti-rotation slot 3.1 is provided at the bottom of the groove 3.5. A clearance groove 3.4 is formed on the groove wall of the groove 3.5. The groove 3.5 is used to place the wire harness grounding terminal 2. When a wire harness grounding terminal without an anti-rotation slot is placed in the groove 3.5, the groove wall can provide... The two side walls of the wire harness grounding terminal provide limiting. When a wire harness grounding terminal with an anti-rotation claw at one end is placed in the groove 3.5, the anti-rotation claw of the wire harness grounding terminal can be engaged with one end of the groove 3.5. When a wire harness grounding terminal with an inclined anti-rotation claw is placed in the groove 3.5, the anti-rotation claw of the wire harness grounding terminal can be connected with the anti-rotation slot 3.1, and the protruding part of the wire harness grounding terminal can be located in the relief slot 3.4, thereby preventing different wire harness grounding terminals from rotating.

[0030] In order to meet the installation and anti-rotation requirements of different wire harness grounding terminals, an anti-rotation structure is provided on the upper part of the grounding installation part body 3 in this embodiment. The anti-rotation structure includes an anti-rotation slot 3.1, a groove 3.5 and a clearance groove 3.4.

[0031] The groove 3.5 is formed downwards from the upper surface of the grounding mounting component body 3. The groove opening is located on the upper surface of the grounding mounting component body 3, and the groove penetrates the front and rear end faces of the grounding mounting component body 3. The groove width of the groove 3.5 is adapted to the body width of the wire harness grounding terminal without anti-rotation claws. Figure 5 As shown, when the grounding terminal of the wire harness without anti-rotation claws is placed in the groove, the two side walls of the body of the grounding terminal without anti-rotation claws contact the two groove walls of the groove, thereby providing a limit for the two side walls of the grounding terminal of the wire harness through the two groove walls of the groove, preventing the grounding terminal of the wire harness without anti-rotation claws from rotating.

[0032] Preferably, the groove is a rectangular groove that extends through the front and rear end faces of the grounding mounting component body, and the width between the two groove walls of the rectangular groove is adapted to the width of the grounding terminal body of the wire harness without anti-rotation claws.

[0033] Since the anti-rotation slot 3.1 and the clearance slot 3.4 are mainly used to provide a limit for the grounding terminal of the wire harness with the inclined anti-rotation claw, this embodiment provides an anti-rotation slot 3.1 at the bottom of the groove 3.5, and the anti-rotation slot 3.1 is at a set angle to the groove wall. Figure 7 As shown.

[0034] Both walls of the groove are provided with clearance grooves. The two clearance grooves are rotationally symmetrical about the center of the groove. The inner wall of the clearance groove is adapted to the outer periphery of the protruding part of the wire harness grounding terminal with inclined anti-rotation claw.

[0035] Two anti-rotation slots 3.1 are provided at the bottom of the groove 3.5. The two anti-rotation slots 3.1 are parallel, and the distance between the two anti-rotation slots 3.1 is equal to the distance between the two anti-rotation claws of the wire harness grounding terminal with inclined anti-rotation claws.

[0036] The clearance groove 3.4 includes an intersecting first clearance edge and a second clearance edge. Both the first clearance edge and the second clearance edge intersect with the groove wall of the groove. The intersection angle between the first clearance edge and the second clearance edge is equal to the outermost apex angle of the protruding part of the wire harness ground terminal. When the wire harness ground terminal with the inclined anti-rotation claw is placed in the groove, the anti-rotation claw of the wire harness ground terminal can be locked in the anti-rotation groove. At the same time, the protruding part of the wire harness ground terminal can extend into the clearance groove, and the two sides of the outermost apex angle of the protruding part contact the first clearance edge and the second clearance edge respectively, thereby providing positioning for the wire harness ground terminal with the inclined anti-rotation claw and preventing the wire harness ground terminal with the inclined anti-rotation claw from rotating.

[0037] In addition, the two clearance grooves are located on both sides of the central axis surface of the groove. The central axis surface of the groove passes through the center of the groove, is perpendicular to the groove, and is parallel to the front and rear faces of the grounding mounting part body 3.

[0038] When the component disclosed in this embodiment is connected to a wire harness grounding terminal with an anti-rotation claw at one end, the wire harness grounding terminal with the anti-rotation claw at one end is placed in a groove. The anti-rotation claw of the wire harness grounding terminal can lock onto one end of the groove, thereby preventing the wire harness grounding terminal from rotating. Figure 6 As shown.

[0039] At this time, the limiting bend of the wire harness ground terminal with an anti-rotation claw at one end is located between the two groove walls of the groove, and can still provide a limit for the wire harness ground terminal through the two groove walls to prevent the wire harness ground terminal from rotating.

[0040] Therefore, this embodiment can fix and prevent rotation of various wire harness grounding terminals by setting grooves, anti-rotation slots and clearance slots.

[0041] To address the issue that connecting the grounding mounting component body 3 to the vehicle body supporting component 4 requires bolt clearance holes on the vehicle body supporting component 4, thus failing to meet the waterproofing requirements of the vehicle interior, this embodiment provides two protruding structures 3.6 at the lower part of the grounding mounting component body 3. These two protruding structures 3.6 are located at both ends of the grounding mounting component body 3, and both are used for connection to the vehicle body supporting component 4. When the two protruding structures 3.6 are connected to the vehicle body supporting component 4, a hollow space is formed between the two protruding structures 3.6, the grounding mounting component body 3, and the vehicle body supporting component 4.

[0042] The wiring harness grounding terminal is connected to the grounding mounting part body 3 by a connector, with one end of the connector located above the wiring harness grounding terminal and the other end located in the hollow space between the grounding mounting part and the vehicle body load-bearing part.

[0043] Preferably, a threaded hole 3.2 is provided on the body 3 of the grounding mounting part, and the threaded hole 3.2 is used to connect with the connector; the threaded hole 3.2 is located at the center of the groove.

[0044] This embodiment discloses a vehicle body grounding mounting part. A groove is provided on the upper part of the grounding mounting part body, an anti-rotation slot is provided at the bottom of the groove, and clearance slots are provided on the groove walls. When the wire harness grounding terminal is placed in the groove, the groove, slot and clearance slot can limit the different wire harness grounding terminals to prevent the wire harness grounding terminals from rotating, thereby meeting the anti-rotation requirements of different wire harness grounding terminals.

[0045] Example 2

[0046] In this embodiment, a vehicle body grounding fixing component is disclosed, such as... Figures 3-8 As shown, the device includes a vehicle body grounding mounting component, a wiring harness grounding terminal, and a vehicle body supporting component as disclosed in Embodiment 1. A protruding structure of the vehicle body grounding mounting component is connected to the vehicle body supporting component 4. The wiring harness grounding terminal is placed in a groove of the vehicle body grounding mounting component and connected to the body of the grounding mounting component via a connector. When the wiring harness grounding terminal is a wiring harness grounding terminal without anti-rotation claws, the groove wall provides limiting for the two side walls of the wiring harness grounding terminal. When the wiring harness grounding terminal is a wiring harness grounding terminal with anti-rotation claws at one end, the anti-rotation claws of the wiring harness grounding terminal are engaged with one end of the groove. When the wiring harness grounding terminal is a wiring harness grounding terminal with inclined anti-rotation claws, the anti-rotation claws of the wiring harness grounding terminal are connected to the anti-rotation slot, and the protruding part of the wiring harness grounding terminal is located within a clearance groove. Thus, the groove wall, the anti-rotation slot, and the clearance groove can limit the movement of different wiring harness grounding terminals, preventing rotation of the wiring harness grounding terminal.

[0047] In order to enable the grounding fixing assembly disclosed in this embodiment to meet the waterproof requirements of the car interior, the protruding structure is welded to the vehicle body support part 4, and the wire harness grounding terminal is fixed to the grounding mounting part body 3 by a connector. One end of the connector is located above the wire harness grounding terminal, and the other end is located in the hollow space between the grounding mounting part body 3 and the vehicle body support part 4. Therefore, it is not necessary to open an avoidance hole on the vehicle body support part 4, thus meeting the waterproof requirements of the car interior.

[0048] The connector is a fastening bolt 1. The grounding mounting part body 3 is provided with a threaded hole 3.2, and the wire harness grounding terminal 2 is provided with a through hole. The fastening bolt 1 passes through the through hole of the wire harness grounding terminal 2 and connects to the threaded hole 3.2 of the grounding mounting part body 3.

[0049] The length of the fastening bolt 1 extending out of the ground mounting part body 3 is less than the distance between the lower part of the ground mounting part body 3 and the vehicle body load-bearing part 4, so that one end of the fastening bolt 1 is located between the ground mounting part body 3 and the vehicle body load-bearing part 4.

[0050] Preferably, each protruding structure is welded to the body load-bearing part 4 by argon-shielded welding on both sides to form a weld 3.3, which solves the problem that the aluminum alloy body cannot withstand high torque, ensuring reliable connection and avoiding waterproofing problems caused by opening holes in the interior floor of the vehicle body to avoid fastening bolts.

[0051] The vehicle body grounding fixing assembly disclosed in this embodiment connects the wiring harness grounding terminal to the grounding mounting part through a connector. A protruding structure is provided on the lower part of the grounding mounting part body, and the protruding structure is connected to the vehicle body load-bearing part. This allows the end of the connector to be located between the grounding mounting part and the vehicle body load-bearing part, thereby eliminating the need to drill bolt clearance holes on the vehicle body load-bearing part and thus meeting the vehicle's interior waterproofing requirements.
